Yes, except there used to be an extremely readable bar that would let you see the like/dislike ratio at a glance.
Sure, you and I can do the math, establish a threshold value above which a video is worth watching (this was _much_ more intuitive with a like:dislike ratio btw), and compare that for each video. But can your mom do that? Can your kids do that? Can you do that while drunk? Can you do that with mind fog and high fever from Covid? Can you do that during a schizophrenic episode? Can you do that when you have early stage dementia?
This change is an attack on the people most susceptible to manipulation. I am outraged that you're making up excuses.
1:9 was merely an example of a video that is likely to be garbage or highly controversial (with exceptions, namely COVID & governmental videos), there was also a visual bar indicating where it sits at for people who find it hard to tell which number is larger than the other. That ratio was irrespective of engagement which is highly variable per video, creator or topic. To pretend it conveys the same amount of information is plain disingenuous for the sake of it.
